The perspectives of the improvement of natural science and technology education remains actual at all levels of an education system. Rapid development of science and technologies creates new challenges for an education system. Undoubtedly, natural science and technology education is a major factor of economic development of society. Deep concern is created by that fact that in some countries the tendency of decrease in the interest of youth to science in general is observed. It is obvious that it is necessary to reconsider the existing strategies of natural science and technology education. In this regard it is important to develop qualitatively new strategies and techniques of teaching and learning. A key task, there is a development of professional competences of science teachers, systemic improvement of teacher education in universities. Two important events are briefly presented in this editorial. The first Baltic Symposium on science and technology education was organized in Lithuania in June 2015. During the symposium participants shared experience, presented the latest scientific researches, and also examined some perspectives of natural science and technology education in the Baltic States. The second event is scientific methodical conference “Natural Science Education in a Comprehensive School” which is focused on school practice. It was organized in the Veisiejai gymnasium in April 2015. The presented scientific events undoubtedly have an influence on a development of science and technology education in general. Key words: science and technology education, scientific conference, school practice.


Nanotechnology is the investigation of tiny designs, having size of 0.1 to 100 nm. Nano medication is a generally new field of science and innovation. Brief clarification of different sorts of drug nano frameworks is given. Nanotechnology is serving to significantly improve, even alter, numerous innovation and industry areas: data innovation, energy, natural science, medication, country security, sanitation, and transportation, among numerous others. The present nanotechnology tackles current advancement in science, physical science, materials science, and biotechnology to make novel materials that have interesting properties on the grounds that their designs are resolved on the nanometer scale. Ongoing advances in Nano science and nanotechnology plan new and inventive applications in the food business. Nanotechnology presented to be a productive strategy in numerous fields, especially the food business and the space of utilitarian food varieties. However just like the condition with the development of any original food handling innovation, food bundling material, or food fixing, extra investigations are expected to exhibit the possible advantages of nanotechnologies and designed nanomaterial intended for use in food varieties without antagonistic wellbeing impacts. Nano emulsions show various benefits over customary emulsions because of the little beads size they contain: high optical lucidity, phenomenal actual consistency against gravitational parcel and drop aggregation, and further developed bio-availability of typified materials, which make them appropriate for food applications.

The first technological revolution, in the fourth millennium BC, was followed by immense social progress. The second revolution, which is now taking place, could lead to an even greater development in the human sciences, by setting men free from their daily struggle for existence while simultaneously exacting high social standards. Natural law - the “marriage between the ways of heaven and the ways of earth” of the Chinese - represents a route to such progress. In natural science and technology, natural law demands that conclusions be based on observation rather than speculation. The social sciences would do well to follow this example.
